Atomic-Scale Sliding Friction on Graphene in Water

The sliding of a sharp nanotip on graphene completely immersed in water is investigated by molecular dynamics (MD) and atomic force microscopy. MD simulations predict that the atomicscale stick−slip is almost identical to that found in ultrahigh vacuum. Furthermore, they show that water plays a pure...
